Android fans have been waiting for Bethesda’s smash hit mobile gem since its inception this June. The game tasks players with becoming the next greatest overseers by building the most efficient vault and manipulating the people inside to perform optimally. If that means you’re expected to keep all the women in the vault pregnant to populate your vault, that’s what you’re going to do.

Fallout Shelter was a smash hit on iOS, making $5.1 million in just two weeks from the sale of 99 cent “lunchboxes” via microtransactions. Despite this, Bethesda’s Todd Howard was adamant the base-builder was not meant to be a cash cow, stating that its success shows fans “reward the people who make” games.

Fallout Shelter was originally released moments after announcement during their first E3 address. It will therefore be interesting to see if there is anywhere near as much success this close to the release of Fallout 4.

Fallout 4, the next real installment in the franchise releases for PC, Xbox One and PS4 this November.
